About These Birds
European Roller
因求偶时的翻滚飞行而得名。欧洲唯一的佛法僧科鸟类。种群数量下降。
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
